Here's the log from the infamous commit.
Changes to syntax of .ops files and refactoring of ops2c*.pl and
pbc2c.pl.
* Removed ops2c-prederef.pl
* (unrelated) Removed vestigial Parrot/Opcode.pm file.
* Added Parrot/OpTrans.pm, Parrot/OpTrans/C.pm (needed for old
functionality of ops2c.pl), Parrot/OpTrans/CPrederef.pm (needed
for old functionality of ops2c-prederef.pl), and
Parrot/OpTrans/CGoto.pm (needed for functionality of pbc2c.pl).
"OpTrans" == "Op Transformation"
* Makefile.in modifications to call "ops2c.pl C" where it used
to be just "ops2c.pl", and "ops2c.pl CPrederef" where it used
to be "ops2c-prederef.pl".
* core.ops and obscure.ops changes to syntax. Semantics are
identical with previous version:
return HALT --> HALT()
return AUTO --> goto NEXT()
return RETREL(...) --> goto OFFSET(...)
return RESTART(*) --> restart NEXT()
Also, pop_generic_entry() stuff (local var + 5 lines of code)
for dest-less branch ops replaced with new notation "goto POP()",
which uses the new pop_dest() function in stacks.c. This also
allowed these ops to become 'inline' ops, since they no longer
have local variables.
The 'ret' op also became simplified to just "goto POP()", and
also became an inline op.
* interpreter.c reflects the change in type name:
prederef_op_func_t --> op_func_prederef_t
that occurred in include/parrot/op.h
* make_vtable_ops.pl uses "goto NEXT()" where it used to use
"return AUTO".
* ops2c.pl is now generic. Its first argument is the last
package name component of a subclass of Parrot::OpTrans. These
subclasses all have full names of the form Parrot::OpTrans::*.
An instance of the class is created and later consulted for
various bits of information needed to generate the C code.
* pbc2c.pl now uses an instance of Parrot::OpTrans::CGoto to
contain its transformation rules.
* stacks.c has a new function pop_dest() that pops a destination
off the control stack. include/parrot/stacks.h has the prototype.
* Parrot/Op.pm now supports the syntax generated by Parrot::OpsFile
for the "goto POP" case.
Also, the source() method now expects its second argument to be
an object that ISA Parrot::OpTrans. Methods of this object are
called to perform the substitutions.
* Parrot/OpsFile.pm supports the change in notation mentioned
above.
* docs/intro.pod reflects these changes.
* include/parrot/op.h: Renamed type prederef_op_func_t to
op_func_prederef_t because it made the implementation of the
shared ops2c.pl easier.
